Generalisability of the results of the Dutch–Belgian randomised controlled lung cancer CT screening trial (NELSON): Does self-selection play a role

Lung Cancer, 03/30/2012Van der Aalst CM et al.

Both the respondents of the first questionnaire as well as the randomised population of the NELSON trial appeared to differ slightly on smoking characteristics, but the differences were limited and probably balance each other. Results of the NELSON trial will be roughly applicable to the Dutch and probably other populations that fulfil the selection criteria.
